DETAILED DESCRIPTION

The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

The described embodiments of the invention provide an arrangement for an aircraft cabin and seat assemblies that may be used in such an arrangement. While the seat assemblies are discussed for use with aircraft seats in an aircraft cabin, they are by no means so limited. Rather, embodiments of the seat assemblies may be used in passenger seats or other seats of any type or otherwise as desired. As used herein, “TTL” stands for “taxiing, take-off, and landing.” As is known in the art, various aviation regulations prescribe that passengers be in an upright position, or TTL position, at various time periods during travel.

In some embodiments, disclosed is a cabin arrangement for a passenger vehicle, such as an aircraft. The arrangement can comprise a first seating area and a second seating area. In other embodiments, disclosed are seat assemblies. Some seat assemblies can comprise a passenger seat shell having a bench and a backrest, and the backrest can include an upright portion and a resting portion. Other seat assemblies can comprise a modular seat body and a privacy shell.

Referring to FIGS. 1A and 1B, in one embodiment, a cabin arrangement 100 for a passenger vehicle is illustrated. In the present embodiment, the cabin arrangement 100 is illustrated as a cabin 102 of an aircraft 104; however, it will be appreciated the cabin arrangement 100 can be utilized in any passenger vehicle including, but not limited to, aircraft, busses, trains, boats, spacecraft, etc. Generally, the cabin 102 comprises a port side 106, a starboard side 108, a forward end 110, and an aft end 112. The cabin 102 defines a lateral direction 124 as a direction extending from the port side 106 to the starboard side 108. The cabin 102 also defines a longitudinal direction 126 as a direction extending from the forward end 110 to the aft end 112. The cabin 102 comprises a floor 114, sidewalls 116, and a ceiling 418 (illustrated in FIG. 4), all of which define an interior of the cabin 102. As is known in the art, the cabin 102 can comprise any number of doors 120 and windows 122.

In some embodiments, the cabin arrangement 100 can comprise a forward lounge area 128 at an area of the cabin 102 towards the forward end 110. In some embodiments, the forward lounge area 128 can comprise a service area 130, such as a bar, serving counter, etc. where a passenger can be served. In other embodiments, the forward lounge area 128 can also define any number of lounge seating areas 132 that include lounge seats 134 and optionally lounge tables 136. In some embodiments, the forward lounge area 128 can comprise stairs 138 providing access to other decks of the aircraft 104.

As illustrated in FIG. 1A, in some embodiments, the forward lounge area 128 comprises a plurality of TTL seats 140 arranged in rows extending in the lateral direction 124. In some embodiments, the TTL seats 140 are configured such that they permanently remain in a TTL position where the backrest of each seat 140 is upright and does not recline. It will be appreciated that the number of TTL seats 140 per row should not be considered limiting on the current disclosure. In some embodiments, some of the TTL seats 140 can be arranged to face the forward end 110 of the cabin 102 and others of the TTL seats 140 can be arranged to face the aft end 112 of the cabin 102. It is also contemplated that in other embodiments, all the TTL seats 140 can face the same end of the cabin 102. In some embodiments, the TTL seats 140 are provided such that passengers in the forward lounge area 128 need not return to their seats in other areas of the cabin 102 during TTL. In other embodiments, the TTL seats 140 are provided such that individuals other than normal passengers may have a place to sit during various time periods.

As illustrated in FIG. 1B, in another embodiment, the cabin arrangement 100 can comprise an aft lounge area 142 at an area of the cabin towards the aft end 112. Similar to the forward lounge area 128, the aft lounge area 142 can comprise a service area 144 and lounge seats 146.

In some embodiments, the cabin arrangement 100 can comprise dividers or separation walls 178A-C. It will be appreciated that the number and the location of the separation walls 178A-C should not be considered limiting on the current disclosure. As illustrated in FIGS. 1A and 1B, the separation walls 178A-C extend in the longitudinal direction 126. In some embodiments, the separation walls 178A-C extend substantially parallel to the longitudinal direction 126; however, it is also contemplated that in various other embodiments, the separation walls 178A-C can be curved, angled, or offset relative to the longitudinal direction 126, or have various other desired shapes. Additionally, it is contemplated that the separation walls 178A-C can be centrally positioned between the port side 106 and the starboard side 108 or offset between the port side 106 and the starboard side 108.

The separation walls 178A-C can be transparent or opaque. In some embodiments, the separation walls 178A-C can be used to display information, light, art work, advertisements, etc. As illustrated in FIGS. 2, 4, 5, and 8, in some embodiments, the separation walls 178A-C are optionally perforated such that light can pass through the separation walls 178A-C.

In certain embodiments, the separation walls 178A-C can be utilized to create additional areas of the cabin 102 or divide areas of the cabin 102 in two. As one non-limiting example, as illustrated in FIG. 1A, the separation wall 178A is positioned between the first seat assemblies 250 of the first seating area 148 and the sidewall 116 at the port side 106 of the cabin 102. In this embodiment, the separation wall 178A can define a public aisle 180 between the separation wall 178A and the sidewall 116 at the port side 106 of the cabin 102. In some embodiments, the public aisle 180 can be an area where passengers can sit or walk without having to walk through the first seating area 148. As illustrated in FIGS. 3 and 4, in some embodiments, the cabin arrangement 100 comprises tables 382 within the public aisle 180.

As another non-limiting example, as illustrated in FIG. 1B, the sidewalls 178B and 178C can be placed between adjacent second seat assemblies 156 of the second seating area 154. In this embodiment, the sidewalls 178B and 178C can be utilized as an extra support for passengers in the adjacent second seat assemblies 156 to lean against. The sidewalls 178B and 178C can also be utilized to provide additional privacy or separation between some of the passengers in the second seat assemblies 156. It is also contemplated that in other embodiments, a plurality separation walls 178 may be positioned such that they overlap in the lateral direction 124. In these embodiments, the plurality of overlapping separation walls 178 may create more than two sections in that area of the cabin 102.
